Unlocking Adventure

Adventure is credited as containing the first "Easter
Egg" for the Atari 2600. This map will help you unlock the
credit screen with Warren Robinett's name. At that time, Atari officials
frowned upon programmers receiving individual credit, so Warren snuck
it in with this hidden method. Map by Maurice Molyneaux [mauricem@bigfoot.com]
